Well relid only works with humbers.
You need to replace the word of the file with a macro.
eg, D:\Project\Images\101-@Text1@.png
Text1 would be a published field that you could type today's name into.
If you want to combine with relid id you could write;
D:\Project\Images\%relid%-@Text1@.png

Subject: Datalinq to first 3 filename characters
Thanks for that!!! Although we aren't on the latest version, I still researched dynamic datalinq, but the real question is whether I can use %relid% to poll only the first 3 characters of the file I need and not the entire string of characters.
If a still is labeled "101-Paris Hilton.png", can I get the program to only see the 101, because tomorrows 101 will be "101-Harry styles" for example. Different file name which would break the datalinq, but same first 3 digits.
I hope that makes sense.

If you are on newer version of XPression you could use dynamic materials and datalinq keys.

The datalinq key can be a value or even you can use %relid% which takes the number relative to your takeID.
Here's a video on datalinq keys.
